Abstract

A method for automatically switching off a display screen of a television device and the television device are provided. The method includes: while the television device is in an activation mode in which the display screen outputs a video output, controlling a camera to continuously capture images of a viewing area; continuously performing a face detection operation to determine a number of faces in individual images captured by the camera; when it is determined that the number of faces in an image is zero, starting a predetermined countdown timer; and when it is determined that the number of faces remains zero in all images captured since the start of the timer till the time instance that the timer reaches zero, controlling the display screen to switch off. The present invention can actively determine the number of users watching the television device, and automatically switch the television device to a display off mode or a standby mode when it is determined that nobody is watching the television of the television device for a predetermined time period, and can operate the television device in a more power-saving manner.

Description

technical field [0001] The invention relates to a method for automatically controlling the audio output of a television device and the television device. Background technique [0002] When powered on, the TV unit will continue to output video / audio signals until it is manually turned off. In some cases, the television device may be outputting video / audio signals even though no one is watching or listening to the content output by the television device, which may result in unnecessary waste of power. [0003] In the past, television devices may have a function that determines a period of time during which no input command (eg, from a remote control or control panel provided on the television device) has been received. When the time period exceeds a predetermined threshold, the television set may automatically turn off. However, there may be situations where one or more users are actually watching television content on the television set without using a remote control or con...
